Heat Deformation Tester for Rubber or Plastic Insulated Wires and Cables

How to use the heat deformation tester ? Heat deformation tester is used to test the degree of heat deformation of materials such as plastics and wire skins. It is also suitable for testing leather, plastic, rubber, cloth, deformation before and after heating. At a specific temperature, the specimen is freely placed in the testing machine for 30 minutes, and then sandwiched between the parallel plates of the machine, the specified load is added, and the temperature is placed for another 30 minutes, and the thickness difference before and after heating is measured by the gauge, the thickness difference is divided by the thickness before heating, in percentage, that is, the deformation rate.

Wewon’s heat deformation testing machine is a powerful tool designed for determining the heat deflection temperature and Vicat softening point temperature of non-metallic materials. Its unique feature of being able to lift and lower the specimen holder at the beginning and end of the test ensures an accurate and reliable result. The machine can be used to test a wide range of materials such as plastics, rubber, nylon, and electrical insulation materials. The test room is equipped with a square window, allowing for easy observation of the specimens during the testing process, enhancing the user’s control over the testing conditions and results.

Choosing the right heat deformation tester for rubber and plastic insulated wires and cables can be overwhelming. This Wewon’s product page will help you understand the features to look for in a heat deformation tester so that you can make an informed decision. Before purchasing a heat deformation testing machine, it’s important to consider the specific application. For example, are you testing the insulation of high voltage power cables or low voltage flexible cords? This will impact the features required in the heat distortion tester, such as maximum current capacity and temperature range. Make sure that any tester you purchase is compatible with your wires and cables.

When shopping for a heat deflection tester, analyze the different models available to determine which one best fits your needs. Compare and contrast the features of each model such as current capacity, temperature range, and testing parameters. You may also want to look into factors such as cost, warranty, and customer service. With a better understanding of the different types of heat deformation testers available on the market, You can make an informed decision that meets your specific requirements.

When looking for the ideal testing device for your applications, it is important to consider additional safety features that the heat deformation testing machine offers. In rubber and plastic insulated materials, overheating can be a real risk. To prevent this, some heat deformation testers provide an over-temperature alarm and auto shutoff feature to alert users when temperatures exceed safe levels. Additionally, many heat deformation testing apparatus also include features such as robust glass separators to protect wires from unnecessary damage and a thermocouple temperature meter to check accuracy.

By the way, It’s important to consider the material being tested and determine the temperature range at which an accurate result can be obtained. Rubber and plastic insulated wires and cables have insulation that varies in thickness and composition, each having its own inertial resistance property, which translates to a different thermal deformation temperature. Calculate what this range is so that you can find a heat deformation tester with the appropriate temperatures to perform your testing successfully.
